drm_pci_alloc() has input of address mask for setting pci dma
mask on the device, which should be properly setup by drm driver.
And leave it as a param for drm_pci_alloc() would cause confusion

For some clocks, the old Ironlake DPLL calculator wold give m/n/p
combinations that didn't match the spreadsheet of what HW validation
tests. Instead, use the G4X DPLL calculator, which does a better job
at it.
So we use the intel_g4x_find_best_pll to calculate the DPLL for CRT/HDMI/LVDS
on ironlake. At the same time to consider the dpll setting for display port, we
add the display port DPLL limit on ironlake, which will directly use the
function of intel_find_pll_ironlake_dp to get the corresponding dpll setting.

it conflicts with some other register settings and can cause problems.

reclocking is supported, so I'm leaving that bit.

This patch adds a new execbuf ioctl, execbuf2, for use by clients that
want to control fence register allocation more finely. The buffer
passed in to the new ioctl includes a new relocation type to indicate
whether a given object needs a fence register assigned for the command
buffer in question.
Compatibility with the existing execbuf ioctl is implemented in terms
of the new code, preserving the assumption that fence registers are
required for pre-965 rendering commands.

drm_ioctl is called with the Big Kernel Lock held,
which shows up very high in statistics on vfs_ioctl.
Moving the lock into the drm_ioctl function itself
makes sure we blame the right subsystem and it gets
us one step closer to eliminating the locked version
of fops->ioctl.
Since drm_ioctl does not require the lock itself,
we only need to hold it while calling the specific
handler. The 32 bit conversion handlers do not
interact with any other code, so they don't need
the BKL here either and can just call drm_ioctl.
As a bonus, this cleans up all the other users
of drm_ioctl which now no longer have to find
the inode or call lock_kernel.

Dirk reports that nothing is displayed on LVDS when using ubuntu 9.1 after
close/reopen the LID. And I also reproduce this issue on another laptop.
After some tests and debug, it seems that it is related with that the
LVDS status is not updated in time in course of suspend/resume.
Now the LID state is used to check whether the LVDS is connected or
disconnected. And when the LID is closed, it means that the LVDS is
disconnected. When it is reopened, it means that the LVDS is connected.
At the same time on some distributions the LID event is also used to put
the system into suspend state. When the LID is closed, the system will enter
the suspend state. When the LID is reopened, the system will be resumed.
In such case when the LID is closed, user-space script will receive the LID
notification event and detect the LVDS as disconnected. Then the system will
enter the suspended state. When the LID is reopened, the system will be
resumed. As the LVDS status is not updated in course of resume, it will cause
that the LVDS connector is marked as unused and disabled. After the resume is
finished,user-space script will try to configure the display mode for LVDS.
But unfortunately as the LVDS status is not updated in time and it is still
marked as disconnected, the LVDS and its corresponding CRTC will be disabled
again in the function of drm_helper_disable_unused_functions after changing
mode for LVDS.
So we had better check and update the status of LVDS connector after receiving
the LID notication event. Then after the system is resumed from suspended
state, we can set the display mode for LVDS correctly.

One problem in i915 hibernate with current legacy pci pm ops is
that after we do freeze, we'll be forced to do resume once again,
which re-init some resources and do modesetting again, that is
unnecessary for hibernate. This patch trys to bypass that.
We can't resolve this within legacy pm framework, but can do it
easily with new pm ops. Suspend (S3) process has also been kept
without change.

i915_gem_object_unbind had the ordering wrong. The other user,
i915_gem_object_put_fence_reg already has the correct ordering.
Results was usually corrupted pixmaps, especially garbled font glyphs
after a suspend/resume (because this evicts everything).
I'm still waiting for the feedback from the bug-reporters, but
because this obviously fixes a bug (at least for me) I'm already

Previously, if there was no firmware available, the DRM would just
disable channel creation from userspace, but still use a single
channel for its own purposes.
With a bit of care it should actually be possible to do this, due
to the DRM's very limited use of the engine. It currently doesn't
work correctly however, resulting in corrupted fbcon and hangs on
a number of cards.

The context programs are *very* simple compared to the ones used by
the binary driver. There's notes in nv40_grctx.c explaining most of
the things we don't implement. If we discover if/why any of it is
required further down the track, we'll handle it then.
The PGRAPH state generated for each chipset should match what NVIDIA
do almost exactly (there's a couple of exceptions). If someone has
a lot of time on their hands, they could figure out the mapping of
object/method to PGRAPH register and demagic the initial state a little,
it's not terribly important however.
At time of commit, confirmed to be working at least well enough for
accelerated X (and where tested, for 3D apps) on NV40, NV43, NV44, NV46,
NV49, NV4A, NV4B and NV4E.
A module option has been added to force the use of external firmware
blobs if it becomes required.

drm/radeon/kms: Convert radeon to new ttm_bo_init
drm/ttm: Convert ttm_buffer_object_init to use ttm_placement
This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.
This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.
This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.
This driver is reverse engineered, and is in no way supported by nVidia.
Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.
This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.

This change allow driver to pass sorted memory placement,
from most prefered placement to least prefered placement.
In order to avoid long function prototype a structure is
used to gather memory placement informations such as range
restriction (if you need a buffer to be in given range).
Range restriction is determined by fpfn & lpfn which are
the first page and last page number btw which allocation
can happen. If those fields are set to 0 ttm will assume
buffer can be put anywhere in the address space (thus it
avoids putting a burden on the driver to always properly
set those fields).
This patch also factor few functions like evicting first
entry of lru list or getting a memory space. This avoid
code duplication.
V2: Change API to use placement flags and array instead
of packing placement order into a quadword.
V3: Make sure we set the appropriate mem.placement flag
when validating or allocation memory space.

Sometimes we will use a crtc for integerated LVDS, which is different with
that assigned by BIOS. If we want to get flicker-free transitions,
then we could read out the current state for it and set our current state
accordingly.
But it is true that if we aren't reading current state out, we do need
to turn everything off before modesetting. Otherwise the clocks can get very
angry and we get things worse than a flicker at boot.
In fact we also do the similar thing in UMS mode. We will disable all the
possible outputs/crtcs for the first modesetting.
So we disable all the possible outputs/crtcs before entering the KMS mode.
Before we configure connector/encoder/crtc, the function of
drm_helper_disable_unused_function can disable all the possible outputs/crtcs.

of snooping the command stream this allows finer grained

The primary user for this functionality is virtual hardware

be notify. There is also real hardware like DisplayLink and

The vmwgfx driver has a per master rw lock around TTM, to guarantee
mutual exclusion when needed.
This is typically when all evictable buffers are evicted due to
1) vt switch
2) master switch
3) suspend / resume.
In the multi-master case, on master switch the new master takes the
previously active master lock in write mode, and then evicts all
buffers. Any clients to previous masters will then block on that lock
when trying to validate a buffer. fbdev also acts as a virtual master
wrt this.

This enables the use of interrupts on r6xx/r7xx hardware.
Interrupts are implemented via a ring buffer. The GPU adds
interrupts vectors to the ring and the host reads them off
in the interrupt handler. The interrupt controller requires
firmware like the CP. This firmware must be installed and
accessble to the firmware loader for interrupts to function.
MSIs don't seem to work on my RS780. They work fine on all
my discrete cards. I'm not sure about other RS780s or

registers via IIO, it appears the rv515 atom iio table might not
be fully functional, so adding a readback before doing a write
either provides enough delay to make things resume correctly.

AGP resume was broken since we moved to the new init path,
because we never re-enabled AGP on these systems at resume time.
This patch just calls the AGP resume call which just does the reinit
at resume time like the old path did.
Since AGP is pretty much gpu independant I did it outside
the gpu specific code.

When the framebuffer driver does not publish detailed timing information
for the current video mode, the correct value for the pixclock field is

This adds a page flipping ioctl to the KMS API. The ioctl takes an fb ID
and a ctrc ID and flips the crtc to the given fb at the next vblank.
The ioctl returns immediately but the flip doesn't happen until after
any rendering that's currently queued up against the new framebuffer
is done. After submitting a page flip, any execbuffer involving the
old front buffer will block until the flip is completed.
Optionally, a vblank event can be generated when the swap eventually
happens.

This patch adds a new flag to the drmWaitVblank ioctl, which asks the drm
to return immediately and notify userspace when the specified vblank sequence
happens by sending an event back on the drm fd.
The event mechanism works with the other flags supported by the ioctls,
specifically, the vblank sequence can be specified relatively or absolutely,
and works for primary and seconday crtc.
The signal field of the vblank request is used to provide user data,
which will be sent back to user space in the vblank event.

This implements intel overlay support for kms via a device-specific
ioctl. Thomas Hellstrom brought up the idea of a general ioctl (on
dri-devel). We've reached the conclusion that such an infrastructure
only makes sense when multiple kms overlay implementations exists,
which atm don't (and it doesn't look like this is gonna change).
Open issues:
- Runs in sync with the gpu, i.e. unnecessary waiting. I've decided
to wait on this because the hw tends to hang when changing something
in this area. I left some dummy functions as infrastructure.
- polyphase filtering uses a static table.
- uses uninterruptible sleeps. Unfortunately the alternatives may
unnecessarily wedged the hw if/when we timeout too early (and
userspace only overloaded the batch buffers with stuff worth a few
secs of gpu time).
Changes since v1:
- fix off-by-one misconception on my side. This fixes fullscreen
playback.
Changes since v2:
- add underrun detection as spec'ed for i965.
- flush caches properly, fixing visual corruptions.
Changes since v4:
- fix up cache flushing of overlay memory regs.
- killed require_pipe_a logic - it hangs the chip.

When we are evicting from VRAM->RAM we allocate the ttm object,
but we don't set the caching policy on it before blitting into it.
This means on AGP we end up blitting into cached pages, and
the CPU later flushes out on top of them. This was mostly seen as
font corruption.
The other question is why we don't evict VRAM->GTT in a lot of cases,
this would save us some cache transitions since a lot of objects
that are evicted from VRAM will probably end up being pulled back in
a few operations later, and evicting them to system memory involves
2 unnecessary cache transitions.

In commit c1c7af6089 ("drm/i915: force
mode set at lid open time") the intel graphics driver was taught to
restore the LVDS mode on lid open.
That caused problems with interaction with the suspend/resume code,
which commonly runs at the same time (suspend is often caused by the lid
close event, while lid open is commonly a resume event), which was
worked around with in commit 06891e27a9
("drm/i915: fix suspend/resume breakage in lid notifier").
However, in the meantime the lid event code had also grown a user event
notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915:
generate a KMS uevent at lid open/close time"), and now _that_ causes
problems with suspend/resume and some versions of Xorg reacting to those
uevents by setting the mode.
So this effectively reverts that commit 06324194ee, and makes the lid
open protection logic against suspend/resume more explicit. This fixes
at least one laptop. See
http://bugzilla.kernel.org/show_bug.cgi?id=14484
for more details.
